Verstellbacken für Flügelzellenptunpe (Zusatz zu Patent Nr. . ... ... Az.: P 15 53 037*7)Adjusting jaws for vane cell option (addendum to patent no. ... ... Az .: P 15 53 037 * 7)
Die Erfindung bezieht sich auf die Verstellbacken zur Regelung der Fördermenge von FlügelZellenpumpen nach Patent Nr. ...The invention relates to the adjustable jaws for regulating the flow rate of vane pumps according to patent no. ...
Az.: P 15 53 037.7·Ref .: P 15 53 037.7
Es sind schon bei einer regelbaren, druckentlasteten Flügelzellenpumpe mit in einem Rotor radial verschiebbaren Schaufeln Verstell- bzw. Laufbacken vorgeschlagen worden, bei denen die halbkreisförmigen Aussparungen der Laufbacken hinter dem Bereich der Auslaßschlitze in die Form einer archimedischen Spirale übergehen, welche in einer mit ihr tangierenden Geraden zu einer Spitze auslaufen.It is already with an adjustable, pressure-relieved vane pump with radially displaceable blades in a rotor adjusting or running jaws have been proposed in which the semicircular recesses of the jaws behind the Area of the outlet slots merge into the shape of an Archimedean spiral, which is in a straight line tangent to it taper to a point.
Auf dieser Anordnung baut nun die Erfindung auf und hat sich die Aufgabe gestellt, einen vorzeitigen Verschleiß an den scharfkantigen Übergangsstellen der Verstellbacken zu verhindern. Zur Erfüllung dieser Aufgabe schlägt die Erfindung vor, daß die eine Seitenfläche des Laufbackens mit einer Führungsleiste und die andere Seitenfläche mit einer Führungsnut versehen ist. Außerdem wird vorgeschlagen, daß die halbkreisförmige Aussparung an ihrem zur Spitze auslaufendem Ende mit einem Radius versehen ist.The invention is now based on this arrangement and has become set the task of preventing premature wear at the sharp-edged transition points of the adjustable jaws. To achieve this object, the invention proposes that one side surface of the running jaw with a Guide bar and the other side surface is provided with a guide groove. It is also suggested that the semicircular Recess is provided with a radius at its end tapering to the tip.
Die Erfindung ist nachfolgend beschrieben und gezeichnet, so daß auch hieraus Merkmale und Maßnahmen entnehmbar sind. Es zeigen:The invention is described and drawn below so that features and measures can also be taken from it . Show it:

Flg. 3 einen Schnitt entlang der Linie XII-III gem. Fig. 1.Flg. 3 shows a section along the line XII-III according to FIG.
Der Lauf- bzw. Verstellbacken 300, der das Fördervolumen der Flügelzellenpumpe regelt, trägt an einem Ende 301, welches zu einer Gleitfläche geschliffen ist, eine Führungsleiste 302, die mit Schiebesitz in der Führungsnut JOk des Gegenbackens gleitet. Das andere Ende 303 des Verstellbackens 300 ist mit einer Führungsnut JOk versehen. Diese Anordnung von Leiste 302 und Nut 30k ist in der Symmetrie so getroffen, daß zwei dieser Verstellbacken den Förderraum bilden und somit zur Komplettierung des letzteren nur eine einzige Konstruktion des Verstellbackens erforderlich ist. Um weitgehendst Verschleißstellen zu vermeiden, wird die Spitze 306 der halbkreisförmigen Aussparung 305 mit einem Radius 307 versehen. Führungsnut 30^ und Führungsleiste 302 sind so toleriert, daß sie mit Schiebesitz ineinander gleiten können und außerdem die Förderflügel der Pumpe im gesamten Verstellbereich der Backen 301 immer fugenlos entlang der Förderrauminnenfläche schleifen können«The running or adjusting jaw 300, which regulates the delivery volume of the vane cell pump, has at one end 301, which is ground to a sliding surface, a guide strip 302 which slides with a sliding fit in the guide groove JOk of the counter-jaw. The other end 303 of the adjusting jaw 300 is provided with a guide groove JOk . The symmetry of this arrangement of bar 302 and groove 30k is such that two of these adjusting jaws form the conveying space and thus only a single construction of the adjusting jaw is required to complete the latter. In order to largely avoid wear points, the tip 306 of the semicircular recess 305 is provided with a radius 307. Guide groove 30 ^ and guide strip 302 are tolerated so that they can slide into one another with a sliding fit and, moreover, the pump vanes can always drag seamlessly along the inner surface of the pumping chamber in the entire adjustment range of the jaws 301 «
